Answer:

To write the expanded form of : 73,489.

Expanded Number Notation: To write a number is to show the value of each digit.

As a sum of each digit multiplied by its matching place value ( i.e, ones, tens, hundreds, thousands etc.)

Then, the expanded form of number 73,489;

$73,489 = (7\times 10000)+(3 \times 1000)+(4 \times 100)+(8 \times 10) + (9 \times 1)$

= $70,000+3000+400+80+9$

Therefore, the expanded form of number

73,489= $70,000+3000+400+80+9$

Paula has a dog that weights 3 times as much as Carla's dog. The total weight of the dogs is 48 pound. How much does Paula's dog

tiny-mole [99]

Paula's dog is 36 lbs

Use the equation 48=3x+x

Add like terms: 48=4x

Divide: 12=x (x=Carla's dog's weight)

Then Multiply x by 3 to get Paula's dog's weight and you get 36 lbs

Radioactive Waste The rate at which radioactive waste is entering the atmosphere at time t is decreasing and is given by Pe^-kt,

Dmitry_Shevchenko [17]

Answer:

$\displaystyle{\int^{\infty}_0 {50e^{-0.04t}}\, dt}=1250$

Step-by-step explanation:

Given:

$T =\displaystyle{\int^{\infty}_0 {Pe^{-kt}} \, dt}$

where,

T = total amount of waste

P = 50, the initial rate

k = 0.04

t = time

$T =\displaystyle{\int^{\infty}_0 {50e^{-0.04t}} \, dt}$

now we need to solve this integral!

$T =\displaystyle{50\int^{\infty}_0 {e^{-0.04t}} \, dt}$

$T = \left|50\left(\dfrac{e^{-0.04t}}{-0.04}\right)\right|^{\infty}_0$

$T = \left|-1250e^{-0.04t}\right|^{\infty}_0$

$T = (-1250e^{-0.04(\infty)})-(-1250e^{-0.04(0)})$

when any number has a power of negative infinity it is 0. because: $a^-{\infty} = \dfrac{1}{a^{\infty}} = \dfrac{1}{\infty} = 0$ , like something being divided by a very large number!
